If the sensors detect a static
object, such as a wall, in the
traveling direction of the
vehicle and the system
determines that a collision
may occur due to the vehi-
cle suddenly moving for-
ward due to an accidental
accelerator pedal opera-
tion, the vehicle moving the
unintended direction due to
the wrong shift position
being selected, or while
parking or traveling at low
speeds, the system will
operate to lessen the impact
with the detected static
object and reduce the
resulting damage.

■Detection range of the Parking
Support Brake function (static
objects to the front and
rear/static objects around the
vehicle
*)*: Vehicles with Advanced Park
The detection range of the Parking
Support Brake function (static
objects to the front and rear/static
objects around the vehicle) differs
from the detection range of the intui-
tive parking assist ( P.363). There-
fore, even if the intuitive parking
assist detects an object and pro-
vides a warning, the Parking Sup-
port Brake function (static objects to
the front and rear/static objects
around the vehicle) may not start
operating.
■Situations in which the system
may not operate properly
 P.366
■Situations in which the system
may operate even if there is no
possibility of a collision
 P.367
■Situations in which the system
may operate even though there
is no possibility of a collision
(static objects around the vehi-
cle) (vehicles with Advanced
Park)
In addition to the situations in which
stationary objects front and rear
(  P.390) may not be detected,
objects may not be detected by the
sensors in the following situations:
●When moving sideways, such as
when parallel parking ( P.408)
■Detection of objects along the
sides of the vehicle (static
objects around the vehicle)
(vehicles with Advanced Park)
●Objects along the sides of the
vehicle are not instantaneously
detected. The location of objects in relation to the vehicle is esti-
mated after they are first detected
by the front or rear side sensors,
or side cameras. Therefore, after
the power switch is changed to
ON, even if an object is along the
side of the vehicle, it may not be
detected until the vehicle has
been driven a small amount and
the side sensors or side cameras
completely scan the areas along
the sides of the vehicle.
●If a vehicle, person, animal, etc., is
detected by a side sensors or side
cameras, but then leaves the
detection area of the side sensors
or side cameras, the system will
assume the object has not moved.

right or left at the rear of the vehi-
cle at a traveling speed of approx-
imately 5 mph (8 km/h) or more.
• The shift position is in R.
• The Parking Support Brake deter- mines that a stronger than normal
brake operation is necessary to
avoid a collision wit h an approach-
ing vehicle.
●Brake control
• Hybrid system output restriction
control is operating
• The Parking Support Brake deter- mines that an emergency brake
operation is necessary to avoid a
collision with an approaching vehi-
cle.

The detection area of the Parking
Support Brake function (rear-cross-
ing vehicles) differs from the detec-
tion area of the RCTA function
(  P.374). Therefore, even if the
RCTA function detects a vehicle
and provides an alert, the Parking
Support Brake function (rear-cross-
ing vehicles) may not start operat-
ing.

If the rear camera sensor
detects a pedestrian behind
the vehicle while backing up
and the system determines
that the possibility of collid-
ing with the detected pedes-
trian is high, a buzzer will
sound. If the system deter-
mines that the possibility of
colliding with the detected
pedestrian is extremely
high, the brakes will be
applied automatically to
help reduce the impact of
the collision.
